Description

The present invention relates to the field of simulation methods and simulation software. More particularly, it relates to the field of electrical simulation and simulation software for electrical and thermal output energy, equipment installation costs, operating costs, and CO 2 emissions in systems supplying electrical and thermal energy.

Single use of wind power generators, solar power generators, solar heat collectors, and cogeneration devices for consumer, commercial, and educational facilities for the purpose of reducing costs, energy consumption, or carbon dioxide (CO 2 ) emissions There are many introduction plans / simulation examples (for example, Non-Patent Documents 1, 2, and 3) for systems that are used together or combined (in the case of hybrid devices), and there are different installation targets for each facility. Using independent simulation methods and conditions, electrical and thermal output energy, equipment installation cost, operating cost, CO 2 emission, etc. when the system is introduced are calculated.

For example, in Non-Patent Documents 4, 5, and 6, electrical and thermal output energy, equipment installation cost, operating cost, CO 2 when the system is introduced in a facility where power and heat demand data are measured in advance. Emissions are calculated.

  Regarding the introduction of cogeneration equipment, the program “CASCADE” for evaluating the effects of cogeneration introduction introduced in Non-Patent Document 7 includes (1) Load data for 5 buildings including hotels and hospitals. (2) Can synthesize load data and can be used for multi-use buildings. (3) Each system of gas engine, gas turbine, and fuel cell can be evaluated. (4) One year (12 months) Calculate energy every hour on the representative day of the month. (5) For operation, both power load tracking and thermal load tracking modes can be evaluated. (6) Power purchase control amount, generator load factor, operating time Can set detailed conditions such as use of exhaust heat, (7) Can evaluate a system incorporating a hot water tank, (8) Can also evaluate reverse power flow when surplus power is sold, 9) energy saving, economical, environmental resistance could be evaluated, it has a characteristic that has been standardized (10) as a graphical output of the calculation result menu.

  In Non-Patent Document 8, in facilities where power and heat demand data has not been measured in advance, the power and heat demand for each month / business holiday is entered by inputting information such as the type of business using the power and / or heat demand model pattern. There has been proposed a program having a function for automatically creating a pattern and a function for automatically capturing measurement data of a power demand pattern when it is electronically available. In addition, it is possible to optimize a system including a storage battery, a cogeneration system, a boiler, a refrigerator, and a heat pump. (1) Cogeneration equipment: gas turbines, gas engines, and diesel engines, (2) boilers: steam boilers and hot water boilers, (3) refrigerators: electric, steam absorption, and direct absorption, 4) Heat pump: both hot and cold. Moreover, the simulation about the apparatus which can select an electric main and a heat main as an operation mode of a cogeneration apparatus is possible.

Non-Patent Document 9 proposes a system that controls a microgrid including a fuel cell, a storage battery, and a hot water tank, assuming an apartment house or a detached house. This control system has functions such as demand forecasting and supply and demand planning. In the demand prediction, the past power / heat demand record of each house is analyzed, and the demand in 30 minutes over 24 hours according to the weather forecast of the next day taken from outside is predicted. In the supply and demand plan, the start / stop time of the power source (fuel cell) and the storage battery charge / discharge amount are set to 1 a day so as to minimize the CO 2 emission amount of the entire site (here, the house) with respect to the demand forecast. Plan times.

Non-Patent Document 10 proposes a system for drafting an optimum plan for electric power supply and demand for one week in the future every 30 minutes for electric heat demand in an existing microgrid. This system obtains electric power demand prediction, natural energy output prediction, and generation amount of sewage sludge digestion gas as an energy source from past results and weather forecast information as input conditions for optimization of supply and demand operation plan.

  However, when calculating the simulation of the introduction of the system to a specific facility in detail, unless a cogeneration system is used and a power and heat supply system is assumed, use a separately created calculation program. Or rely on very simple approximation calculations.

  In addition, when simulating the operation of the system retroactively, it is necessary to use past accumulated measurement demand data or use a power and heat demand model pattern prepared in advance. In many cases, the power and heat demand model pattern prepared in advance is a record of hourly power and heat demand on the representative day of each month of one year (12 months), and does not take into account differences in weather conditions .

  Further, when simulating the operation of the system retroactively, the assumed operation method is limited to power load tracking and heat load tracking, and a more flexible and highly efficient operation method is not implemented in the simulator.

  In addition, the software shown in Non-Patent Documents 9 and 10 for planning the operation method of the cogeneration device and the power supply device using the weather forecast and the demand prediction is applied only to a specific system configuration designated by the software producer. And cannot be used in facilities where the system is already installed.

  In addition, since the places where past weather data are accumulated and the places where weather forecasts are published are limited, when simulating the system at any point throughout the country, the past is quite different from the actual Weather data and weather forecasts will be used.

The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to provide a facility in advance in a facility where the system is to be introduced or a facility in which the system is introduced. Even if past accumulated meteorological data and / or past accumulated demand data of facilities are not accumulated, simulation using past estimated weather data and / or past estimated demand data, past estimated weather data and / or past estimated demand Obtain as much electrical and thermal output energy as possible through simulation using data and weather forecasts and demand forecasts, reduce equipment installation costs as much as possible, reduce operating costs as much as possible, and CO 2 emissions as much as possible Get a combination that reduces (best matching It is an object of the present invention to provide a user-friendly simulation method and simulation software.

  The present invention relates to a device scale configuration of a system that uses a wind power generator, a solar power generator, a solar heat collecting device (manufacturing device such as hot water) and a cogeneration device for single use, combined use, or combination (in the case of a hybrid device), and Software for simulating operation methods, consisting of one or more independent or integrated software modules among a weather prediction software module, a power / heat demand prediction software module, and a system configuration / operation method optimization software module It is characterized by being.

  In the simulation method and simulation software of the present invention, an optimal system construction mode for outputting a system configuration optimized or optimized for a facility to which the system is to be introduced, and a facility for which the system is introduced are preferable. It is possible to select an optimum operation command mode that outputs a system operation method that has been converted into a system.

  In the facility where the system is to be introduced, the system configuration / operation method optimizing software module goes back to the past to perform a system operation simulation including a wind power generator, a solar power generator, and / or a solar heat collector. In order to do so, the past accumulated weather data of the point where the facility exists is necessary. However, such data is rarely prepared. The meteorological prediction software module uses an arithmetic unit to empirically estimate past estimated weather data at an unobserved point using available past measured weather data and store it in a storage device.

  In addition, in the facility where the system is introduced, when the system operation method from 1 hour to 24 hours (from 1 hour to 24 hours) is optimized from the present to 24 hours ahead, By predicting future predicted supplyable energy calculated using an arithmetic unit, a predicted use operation optimization function is realized.

  In addition, the weather prediction software module can be used to display any forecasted weather change predicted using a computing device on the screen of a computer or TV, so that the forecasted weather change can be used in daily life or business. It has a forecast weather change graph display function that displays it in a graph format.

  In the facility where the system is to be introduced, when the system configuration / operation method optimizing software module traces the operation of the system retroactively, the past accumulated measurement demand data is required. However, such data is rarely prepared. This software uses the power / heat demand prediction software module to apply past combinations of power and / or heat demand model patterns prepared in advance to past estimated demand data from estimated weather data. Therefore, it is possible to perform a realistic simulation in which electric power and heat demand fluctuate daily according to weather conditions.

  The facility to be simulated is a hotel, a hospital, a large commercial facility, a university, a collective dwelling, a factory, or a combination thereof.

In addition, the system configuration / operation method optimization software module calculates the operation cost based on the power charge system / gas charge system and the inherent constraints in the facility to be simulated, as well as the CO for each energy source. It has a function to calculate CO 2 emissions and primary energy consumption based on 2 emissions intensity and primary energy consumption intensity.

  Further, the constraint conditions are the site area of the facility that is the simulation target, the total floor area, the area where new equipment can be constructed, the presence or absence of thermal piping work, the presence or absence of wind power generators, the presence or absence of solar power generators, It is the presence or absence of introduction of a solar heat collector, the presence or absence of introduction of a cogeneration device, the presence or absence of introduction of a heat storage tank, and the upper limit or lower limit of the installed capacity and quantity of those devices / equipment.

The simulation software and the simulation method of the present invention are included in the system in which the wind power generator, the solar power generator, the solar heat collector, and the cogeneration device are used singly, in combination, or combined (in the case of a hybrid device). Electrical and thermal output energy, equipment installation costs, operating costs, CO 2 emissions by simulating equipment size, configuration, quantity and operating method using forecasted or estimated weather data and power and heat demand data The amount can be best matched more effectively than the prior art.

  In addition, when the operation simulation of the system is performed retroactively, in order to assume the predictive operation optimization function, the power load following operation and the thermal load following operation described in the background art [0004] and [0005] are assumed. Highly efficient and realistic driving simulation is possible.

  In addition, the background technologies [0004] and [0005] simulate the operation of the cogeneration apparatus using the hourly power and heat demand patterns on the monthly representative days of one year (12 months). However, in this software, the past estimated demand data according to claim 5 is converted from the past estimated weather data according to claim 2 by the electric power / heat demand prediction software module according to claims 1, 5, and 6. Since the estimation is made by applying some power and / or heat demand model patterns prepared in advance, a realistic simulation in which the power and heat demands fluctuate daily according to weather conditions is possible.

  The background art [0006] and [0007] can be applied only to a specific power and / or thermal energy supply system. In the present software, the system configuration according to claim 1, 7, and 8 is used. -Gas engine, gas turbine, diesel engine, fuel cell, storage battery, gas boiler, heavy oil boiler, exhaust heat recovery boiler, electric heat pump, gas heat pump, exhaust heat input type heat pump, heat storage tank, built-in operation method optimization module The present invention can be applied to any system as long as the system is a combination of a solar power generation device, a solar heat collection device, and a wind power generation device.

  In addition, the background technologies [0006] and [0007] do not assume demand forecasts and supply-demand plans at unobserved points where past accumulated weather data cannot be obtained or non-forecast points where weather forecasts cannot be obtained. However, this software can predict past forecast weather data at any point in Japan and forecast future weather changes with the weather forecast software module, so that more realistic and accurate demand forecast can be predicted.
